To all whom it may concern:

To render matches immune to the action of moisture'pr'epare a mixture ofresin and beeswax in the proportions of two parts of resin to one partof beeswax, heat the mixture in a vessel until the boiling point isSpecification of Letters Patent.

AppIication filed. March 4,1918. Serial No. 220,394.

Patented Apr. 22, 1919.

found to have adhered to the match which film is impervious to moisture,hard but not friable, and at the same time will not interfere with theignition or burning qualitiesof the matches. The time required for themixture to set is very short as both ingredients are solids.

What I claim is The process of waterprooofing matches, which consists ofdipping them head down ward in a mixture composed of two parts by weightof resin, and one part by weight of beeswax, heated to a temperature afew degrees below boiling, thereby coating the igniting material and thestem portion, all substantially as described.
